I'm hitting on my best friend's wife! How should I control my lust?

Hi, I am a single father. My best friend/neighbor and I have always been really close, but lately tons of stuff has been coming between us (mostly me being jealous of all his success). And one of them is his wife. Now, I am divorced, and lately I haven't been going out much since I can't find a girl. My friend/neighbor is a doctor of some sort, he owns his own practice and is also an author, so he's super wealthy - and super busy. Well, can y lame me for hitting on his wife? She is usually gardening or in their backyard pool, so I see her a lot. At 40 years old, this mother of 4 has retained herself very well! I mean she is SMOKING! She has an amazing body and unimaginably gorgeous features. She's played hostess a lot for her wealthy husband so she's super nice, hospitable, and amiable. On top of that she just oozes charisma and has a fantastic personality (and man can she cook!). Plus, she's alone a lot while her kids are at school and my best friend at work. I have mildly flirted with her and so far she seems to have either not noticed or thought nothing of it. She hasn't rejected me, but she hasn't accepted my advances either. I took it a little farther last night and she openly rejected me, but I told her I was drunk and she forgave me. How can I control myself? I mean I'm lonely and desperate, she's gorgeous and amazing!!!! I know its wrong but I just can't stop! How should I control this???
